OpenMarket Documentation

OpenMarket is an NFT marketplace. OpenMarket is built on three main modules: - Frontend: User can browse, filter, buy, and sell NFTs. - Backend: Indexing NFTs and the corresponding metadata. Keep track of the order book. Provides APIs for the frontend. - Smart-Contract / DEX: Buy trades relay only on blockchain technology. By buying NFTs the user directly interacts over a P2P network with the smart contract without a centralized party.

OpenMarket comes with two different flavors. The public instance and a white label solution. OpenMarket white-label solution is an out-of-the-box NFT-Marketplace for trading NFTs. It’s highly customizable and can be adjusted for customer requirements. OpenMarket works technically on all EVM based blockchains. It’s designed to run on the customers cloud infrastructure and be operated by the customer.
